Found it out: It is called "Type Hinting". http://ch2.php.net/manual/en/language.oop5.typehinting.php There is a user contributed note on that page: "Type hinting allows not to specify a required interface to be supported for the object being passed. Beware, the interpreter will not give an error for that."
